Apple’s iPad led the charge as total worldwide tablet shipments hit a record of 52.5 million units in the fourth quarter of 2012, according toIDC’s preliminary datafrom its Worldwide Quarterly Tablet Tracker, but its market share continued to slide due to competition from Samsung. Meanwhile, PC shipments declined during the quarter for the first time in more than five years. The tablet market grew 75.3% year-over-year, and increased 74.3% from the previous quarter’s total of 30.1 million units, helped along by holiday purchases, lower average selling prices and a wider range of products.“We expected a very strong fourth quarter, and the market didn’t disappoint. New product launches from the category’s top vendors, as well as new entrant Microsoft, led to a surge in consumer interest and very robust shipments totals during the holiday season,” said Tom Mainelli, tablet research director at IDC.Apple shipped a total of 22.9 million units, boosted by the launch of the iPad mini, as well as the fourth generation full-sized iPad. But while Apple’s iPad shipments grew 48.1% over the same quarter last year, Apple’s market share slipped for the second quarter in a row (down to 43.6% from 46.4% last quarter) as number two vendor Samsung continued to nip at the Cupertino company’s heels. Samsung enjoyed 263%, shipping nearly 8 million combined Android and Windows 8 tablets durings the quarter. It still holds 15.1% of the market, the same as from the previous quarter.Competing vendors like Amazon and Barnes and Noble both saw an uptick in their market share thanks to the holiday season. Amazon shipped more than 6 million tablets during the quarter, increasing its share to 11.5% from 8.3% the previous quarter, with year-over-year growth of 26.8%. Barnes and Noble shipped almost a million units, increasing its share up to 1.9% from 0.7%, but its total dropped by 27.7% year-over-year. Microsoft new Surface with Windows RT tablet failed to reach the top five with just short of 900,000 units shipped. IDC said that Microsoft and its partners may need to create smaller devices and lower prices in order to compete because consumers are shying away from more expensive tablets with desktop operating systems.“There is no question that Microsoft is in this tablet race to compete for the long haul. However, devices based upon its new Windows 8 and Windows RT operating systems failed to gain much ground during their launch quarter, and reaction to the company’s Surface with Windows RT tablet was muted at best,” said Ryan Reith, program manager, Mobile Device Trackers at IDC.

I think it's obvious even to the birds outside.. it's happening the same it was happening with phones. In 2-3 years Android rose up and took significant marketshare from Apple and next 2-3 years it will absolutely dominate the tablet market.

I wonder if IDC counts devices like my new Samsung smart pc as a tablet or are we limiting this only to arm devices? I've been using mine as a tablet the majority of the time even though I have the keyboard dock as well.

Either way in these stats it would be counted as a Samsung, not a MS since MS only counts Surface, and even those numbers doesn't seem to be correct.
